Sedum do well in cold weather which tells us that you can plant them a lot earlier in the year than other frost tender plants.

The last month that you can plant sedum and expect a good harvest is probably August. You probably don't want to wait any later than that or else your sedum may not have a chance to really do well. If you are starting your sedum indoors then you might be able to get away with starting them a couple of weeks earlier.
